Textile Yarn Guides
Alumina, titania and zirconia ceramic yarn guides for spinning, winding, twisting, knitting and weaving lines — with groups, codes and dimensions.
A yarn guide — also known in the field as a ceramic eyelet — defines the path the yarn follows on the line, working in continuous contact with the yarn. The eyelet bore and contact radius are chosen for the yarn count (denier/Ne), line speed and wrap angle. In spinning, winding, twisting, knitting and weaving processes the hardness and surface roughness of the guide are among the main determinants of hairiness, filament breaks and variation in yarn quality.
Erginer Seramik has produced technical porcelain since 1952 and manufactures ceramic guides (textile machine ceramics) as a continuation of that work. The yarn guides in the catalogue are produced in alumina, titania and zirconia grades; every product is published with its own code and dimensions.
What the ceramic surface does on a yarn line
Yarn passes over the guide surface at high speed and under tension. The micro-topography of the surface works directly into the yarn: a worn or scratched guide increases hairiness and filament breaks.
- High surface hardness prevents groove formation under continuous yarn passage; the guide form and the yarn path do not change over time.
- Controlled surface roughness (Ra) preserves the yarn structure; hairiness and filament break rates fall to a minimum.
- Soft-surface titania (E-TY) prevents filament breakage; conductive titania (E-TB) prevents static build-up on synthetic yarns.
- The pore-free microstructure has 0% water absorption; the guide is unaffected by moisture and process chemicals.
Guide groups used in textile applications
The groups below cover the guide families used on textile lines; they correspond to the different contact geometries found on spinning, winding, twisting, knitting and weaving lines.
Eyelet Guides
Flanged, through-bored guides for textile machinery and cable-industry ceramics, steering yarn and wire where they pass through the machine.
View
Rolling Guides
Shaft-mounted ceramic rollers with two flanges. They carry the thread line on a turning body wherever yarn or wire changes direction.
View
Take-Off Guides
Flanged ceramic guides with a central bore. Radial channels on the face centre the yarn where it passes through.
View
Slipper Guides
Stepped ceramic guides with a V-groove on the upper face. The yarn slides along inside the channel and stays centred.
View
U Guides
Ceramic guides with a V-shaped mouth on top and a narrow slot through the body. The yarn is threaded by hand and stays in the slot in production.
View
Trap Guides
U-bodied ceramic guides with a claw at the mouth. The yarn goes in easily and the claw stops it slipping back out.
View
Tube Guides
Plain ceramic tubes. Yarn or wire runs through the bore, at machine pass-through points, on wire drawing lines and in cable-industry ceramics.
View
Hook Guides
Ceramic guides with a side hook and a slot. The yarn can be hooked on and released while the machine is running.
View
Rod Guides
Plain ceramic rods. They form the contact surface that yarn or wire runs over at tension and direction-change points.
View
Special Guides
Ceramic guides made to a machine-specific shape. Plates, angled bodies and custom bores belong to this group.
View
Traverse Guides
Arms that traverse the yarn along the bobbin during winding. Supplied as a complete guide built from ceramic, plastic and metal parts.
View
Brake Guides
Spring-loaded brake units that set yarn tension. Supplied complete with a ceramic disc face, a plastic adjusting knob and a metal body.

Material selection: alumina, titania, zirconia
The material is chosen according to line speed, ambient conditions and the mechanical stress on the yarn. E-500 alumina is the optimum solution at high speed and tension; soft-surface E-TY is used to prevent filament breakage, conductive E-TB against static build-up, and zirconia (E-Z) where impact resistance is required. The measured material values are in the data table on the Technical Ceramic page.
Frequently asked questions
What separates a ceramic yarn guide from a metal one?
Surface hardness and roughness control. As a metal guide wears, a yarn groove opens in its surface and hairiness rises; a ceramic surface resists this wear far longer, and the controlled Ra value prevents the yarn from fuzzing and breaking. The measured material values are published on the Technical Ceramic page.
Which yarn types are ceramic guides used with?
With every yarn type, from natural cotton and wool to fine-denier synthetic filaments; the finer the denier, the more the surface finish matters. In synthetic and texturised applications the surface choice matters: soft-surface E-TY prevents filament breakage, conductive E-TB prevents static build-up.
How is static build-up prevented on a yarn line?
The conductive titania grade E-TB prevents static charge accumulation at the contact point; it is used for this purpose on high-speed synthetic yarn lines.
Can a guide be produced in a size not found in the catalogue?
Yes. The "Custom Production Request" button on each product page prepares a message containing the product code; add the dimensions and quantity you need and send it via WhatsApp or e-mail.
Is a ceramic eyelet the same part as a yarn guide?
Yes. The parts referred to in the field as ceramic eyelets are the yarn guides in this catalogue. Naming varies by region and machine type; the part is identified by its code and dimensions.
